“…When the best performance can be quanti fi ed, the overall de fi ciency in yield, due to inferior performance, can be assessed. When it is allied to the knowledge of the components of yield, the position of the boundary line can be used to direct attention to the phase of growth most likely to respond to better management (Walworth et al 1986 ;Bhargava and Sumner 1987 ) .…”

“…Nowadays, most of the research on crop fertilization technologies is mainly focused on plant nutrition diagnosis, soil testing and formulation of fertilizers (Bhargava and Sumner, 1987;Li et al, 2007;Marangoni et al, 2001;Romero et al, 2010;Wheeler and Pickering, 2003). These techniques enable us to learn about and monitor the nutritional status of soil, nutrient uptake, and metabolism levels in plants during growth, thus providing us with certain guidelines for fertilizer application.…”

The application of genetic information in agricultural production is an important issue, which is highly worthy of attention. Gene expression data can accurately reflect the growth and metabolic status of plants, with which we can predict and monitor the nutritional requirements of plants and then derive accurate fertilization strategies. In this study, to verify the feasibility and workability of gene information-based fertilization strategies and to figure out the specific nutritional requirements of grapevine (Vitis vinifera L.) at various developmental stages, the expression levels of 13 N-P-K uptake and metabolism genes and their responses to fertilization during the flowering and berry development stages were validated by using quantitative polymerase chain reaction (PCR). The results showed that in the particular stages where N-P-K uptake and metabolism genes were highly expressed, these genes also showed more positive responses to fertilization and the grape quality was more dramatically improved. This proved the feasibility and workability of this novel fertilization strategy. The nutritional requirements of grapevine during the flowering and berry developmental phases were summarized in terms of gene expression levels, in which grapevine needs more P at the flowering stage, more N at the first berry expansion stage, less nutrient at the seed stone hardening stage, and more P and K at the second berry expansion stage and the veraison stage. The present study is one of the novel and initial findings regarding the application of fertilizers in vineyards for better cultivation of grapevine during common cultural practices. Grapevine is one of the world's most economically important fruit crops (He, 1998;Kong, 2004). It is is highly responsive to the application of fertilizers and has been reported as a heavy feeder of N, P, and K. Fertilization of the soil is one of the most important viticulture techniques, with a great effect on the vineyard yield and the grape quality. Fertilizer application usually results in increased yield; however, excessive or unbalanced applications can have negative effects on the yield and fruit quality. Traditional fertilization strategies are dominantly based on phenology and personal Abbreviations: FE, fertilization; SC, sample collecting; VvAS, V. vinifera asparagine synthetase; VvGDH, V. vinifera glutamate dehydrogenase; VvGS, V. vinifera glutamine synthetase; VvNiR, V. vinifera nitrite reductase; VvNR, V. vinifera Core Ideas• This approach is more accurate and reliable than traditional fertilization strategies.• This study verified the feasibility and workability of gene expression-based fertilization strategies.• The specific nutritional requirements of grapevine at different developmental stages were depicted in the level of gene expression.

“…In peninsular India, grape bud initiation and differentiation is known to be influenced by N, P and K (Bhujbal and Phadnis, 1971;Chadha and Singh, 1971;Chitkara et al, 1972;Manivel and Muthukrishnan, 1977;Nijjar and Chand, 1972), but all investigators did not attempt to relate tissue nutrient content with yield. The relationship between leaf nutrient content and yield has been well established by the classified work of Lundegardh (1951) in cereal crops and that of Cook and Krishaba (1956), Cook and Wheeler (1978), Ulrich (1942), Bhargava and Sumner (1987), Bhargava and Chadha (1993) and Bhargava and Raghupathi (1999) on grapes.…”

“…Investigations have proved that desired status of three primary nutrients leads to desired or targeted potential determination, of course coupled with specific water and hormone management and some other cultural practices. Various investigations on grapes (Bhargava and Sumner, 1987;Bhargava and Chadha, 1993;Bould, 1974;Chundawat et al, 1977, Cook andWheeler, 1978;Faruqi and Satyanarayana, 1975;Manival and Muthikrishnan, 1977) have clearly demonstrated that potential yield is determined in the prior season in peninsular India and is influenced by nutrient levels at the time of fruit bud initiation and differentiation. In peninsular India, grape bud initiation and differentiation is known to be influenced by N, P and K (Bhujbal and Phadnis, 1971;Chadha and Singh, 1971;Chitkara et al, 1972;Manivel and Muthukrishnan, 1977;Nijjar and Chand, 1972), but all investigators did not attempt to relate tissue nutrient content with yield.…”
